Transvesical migration usually results in lower urinary tract symptoms, even in the absence of a secondary bladder stone. The nature of symptoms caused by the migration depends on the destination of the device. The most common sites for IUCD migration are the omentum, rectum, sigmoid colon, peritoneum, and bladder. IUCDs are known for uterine perforation and extrauterine migration, with perforations being reported at a rate of 1.2 to 1. A rare iatrogenic cause of vesicolithiasis (bladder stones) is a migrated intrauterine contraceptive device (IUCD). Vesicolithiasis is a rare condition in an otherwise normal bladder that can be caused by outflow obstruction, chronic or recurrent infections, and intravesical foreign bodies. Radiography and ultrasonography are adequate for the diagnosis of intravesical migration of intrauterine contraceptive devices. The detailed imprint of the device inside the stone and the laminated appearance of the stone material were characteristic of a secondary bladder stone formed around an intrauterine contraceptive device. ConclusionsĪ migrated intrauterine contraceptive device can act as the nidus for the formation of a secondary bladder stone. Our patient was asymptomatic following the surgery. The device and the threads were fully covered with the stone material. After confirming the location of the stone via ultrasonography, a vesicolithotomy was performed, revealing a stone with three limbs corresponding to the shape of the Copper T380A device. She had been completely asymptomatic until she developed lower urinary tract symptoms. Two years after the insertion, it was considered to be missing, but our patient did not comply with the recommended follow-up. The device had been inserted 15 years previously. The radiographs showed a large bladder stone with an imprint of an intrauterine contraceptive device in the center of it. Case presentationĪ 48-year-old Sri Lankan woman underwent a workup for lower urinary tract symptoms and recurrent urinary tract infections over the previous 6 months. Here we describe the case of a large bladder stone formed around a migrated Copper T380A device that was neglected and detected 15 years after insertion. A wide variety of complications due to the extrauterine migration of intrauterine contraceptive devices have been reported in the literature.
